The black streaks on your roof are not dirt. They are gloeocapsa magma, an algae that feeds on the limestone in your shingles. Left alone, it shortens roof life and can flag insurance inspections. Pressure washing a roof destroys it faster than the algae does, which is why we never put pressure on shingles.
Our roof soft wash applies the same solution roofing manufacturers specify, lets it do the work, and rinses at garden-hose pressure. The streaks die on contact and rain carries the residue away over the following weeks.
A clean roof is not cosmetic. It runs cooler, sheds water properly, and adds years to the most expensive surface on your house.

Why not pressure wash a roof?
Pressure strips the granules that protect shingles from UV. Once the granules are gone, the roof is done. Soft wash cleans without touching the granule layer.
How long do results last?
Typically 3 to 5 years, longer with zinc or copper strips installed at the ridge.
Do you clean cedar and metal roofs?
Yes. We adjust solution and method for cedar, metal, and composite roofing.
